F, F, F, vare the countertwisty pulleys,

which'performthe twist bymeans of their peripheries. v"These pulleys'consist each of a? short cylinder of metal with a band` e, of

woolen `clotliwaround Aits periphery. They arey securedupon parallelaxles` a, a, c, which are placed atlright :angles to theaXles of thedrawing. rollers, andparallel tothe rovlng, as `it `passesufrom theVback to thefront axles neXt the front drawing rollers; rand theirperipheries just touch yeach `other lightly. They are 'caused to`revolve all in the samedirection "by bands Z2, from thedrawingrollers,being at those ends of the cylinder C, running overpulleys c, c, c, on

theirtaxles `and each roving passes between two ofthemvat or neartheir'point of contact and ireceives the twist in consequence t of thecontiguous portions of the rollers moving in opposite directions. ingsofthe spindles a, a, are in bridges H, H', secured to the Stop of theframing A. i

i The lfront drawing rollers E, E, E', E, `are placed so' close to thefronts of the The `bearcountertwist pulleys as nearly to `touch 30 them.The bed rollers E, E, are covered and are `made of about theusualdiameter of covered drawing rollers, as covered rollers can notlwell besmallenbut the top` rollers are iiuted and'mde much `smaller-not85 more than half the diameterin order that .they mayget their bite asclose as practicable tothe countertwist pulleys, or nearer thereto thanthe length of the bers.-` The journalsof the' bed rollers work in fixed90 `bearings e, e, and receive rotary=motion by abelt which is not showninthe drawings. The top rollers have their journals working inbearingsin the ends of levers G, G,

which work on X`ed fulcra al, d,in brackets 95 f, 7, secured to theframing. These levers have weights g, g, suspended from them betweentheir fulcra and the top rollers, in

order to draw thetop rollers down upon the bed rollers and give themsutlicient bite.

carrying fingers h, 7u, of which there is one for each spindle of thespinning frame, for the purpose of regulating the countertwist andpreventing too great a degree of twist getting back to the large part ofthe roving near the back drawing rollers, which is done by the fingersgiving an angular direction to the roving as illustrated in Fig. 1,where the roving is represented in red color passing over the finger.The bridge is supported at its ends upon the framing by screws z', z',by which it can be adjusted higher or lower, and the fingers areadjustable separately, being each attached to the bridge by apivot 5, atone end see Fig. l, and having not far from'the said pivot a femalescrew, receiving a male screw j, which rests upon the bridge and servesto raise or lower the finger. By carrying the roving in an angulardirection over the finger It, too much twist is prevented passing thesaid finger toward the back rollers, and the twist is caused to begradual and to increase in about the same proportion as the roving isreduced by drawing, which is the true principle to be observed in woolspinning. Vithout this bridge the countertwist would extend into thefull sized roving to such an extent as to prevent its drawing easily andregularly. The twist can be regulated with great nicety by theadjustment of the bridge and fingers before spoken of to increase ordiminish the angle in the roving; the increase of the angle having theeffect of further preventing the countertwist extending back into thelarge part 0f the roving, and the diminution of the angle having acontrary effect.

The angular directidn may be given to the roving either downward orlaterally instead of upward as shown, by proper arrangeL ments of abridge and fingers or some devices equivalent thereto. In order that instarting or after mending the roving, it may receive a partial twist toenable it to bear being drawn in the angular direction, a sufficientspace is left between the fingers and the bridge, by following thebridge as shown at lo, 7c, in Fig. 4, or otherwise to allow the rovingYto be conducted directly from the back to the front rollers, as showndotted in red color in Fig. 1. As soon as sufficient twist is given, itmerely requires to be passed by hand over the end of the finger on tothe top.

Z, Z, are the spindles driven as usual by bands m, from the maincylinder, n, n, are the bobbins, I, is the ring'plate, and o 0, are thering travelers all of the usual construction. The ring plate is operatedupon to lay the cones on the bobbins in a well known manner by a leverJ, and a cam K, on a shaft M, see Fig. 1; the lever being varied to varythe ring plate by means of a screw L, carrying a nut N, to which thelever is attached; and the said screw receiv ing a constant rotarymotion through a band 79, from a pulley on the shaft M. A drag isproduced upon the ring travelers when winding on the large part of thecones, by means of a series of brushes g, g, which are secured bybinding screws r, 1', in sockets s, s, in a beam O, which extends thewhole length of the frame and is hinged at each end or at properintervals by hinges t, t, to the back of the ring plate. One of thebrushes stands opposite every ring u. The beam O, has a small eye o, atthe back near one end, which receives a rod w, standing up rigidly froma lever P, one end of which works on a liXed fulcrum attached to theframing and the other receives a screw y, which rests upon a cam Q, onthe shaft M. The lever P, receives a vibrating motion from the cam, andthe rod fw, is thereby caused to impart a vibrating motion to the brushbeam O. The cam Q, is so arranged relatively to the cam K, that as thering plate rises the brushes g, g, will fall back from them, and as theplate descends, the brushes advance toward the rings. The brushes are soadjusted by the screwing up or ydown the screw 1', in the lever P, thatwhen the ring plate descends and the winding is being performed on thelower part of the cone, the travelers will during their revolutions comein contact with and receive a drag from theY ends of the brushes. Ast-he ring plate rises and the brush beam falls back, this ydrag will bediminished and finally before the rail reaches the top of its movementthe brushes will leave the traveler quite free. By thus producing a dragon the travelers while winding the large part of the cone, the tensionon the thread, and the tightness of the winding may always be rendereduniform, but without such drag an uniform tension cannot be kept up, asthe traveler will run so much easier while winding the large part thanwhile winding the small part of the cone. The tension may be regulatedexactly by the screw y, in the lever Q. Instead of the brushes g, g,pieces of leather or other soft or elastic material may be used.

The method of regulating the tension of l.the thread during the windingenables a larger bobbin to be used and prevents breakage.

What I claim as my invention and desire to secure by Letters Patentis- 1. Conducting the roving from the back to the front drawing rollersby employing a bridge (or rest) with fingers upon it situated betweenthe front and back pairs of drawing rollers for the purpose of governingthe counter twist, so as to adapt a smaller portion of it to the part ofthe thread nearest the back rollers.
